The integrated objects

The graph object manage all the other ones. It allow to define the default style, the height and width of the drawn graph, the title position

$graph->style ("linePoints")
->width (300)
->height (200);

The data object: manage the input of the data (from array, CSV, JSON). Allow to manage if there is a title on first line or column with autodetection. It also permit to say if the data are stored horizontally or vertically

The title object: manage the title of the graph, with font, size, color and text.

The serie object, provided by the $graph->series->serie ("NAME"), allow to manage the serie. The serie can be drawn on the secondary axis, can have a maximum or minimum value, can have a style different of the general one defined in graph object. It allow to define if the provided data are numerical or labeled
